Abstract
Description
- The present application relates to an arrangement for preparing a liquid developer solution for developing photosensitive material in accordance with the preamble of claim 1.
- In the field of photofinishing technologies, two types of photofinishing environments are mainly known. One of these types concerns minilabs and the other, large scale photofinishing laboratories. In the minilabs, all kinds of processing needed for the exposed film, for the exposure of the photosensitive paper and the development of the exposed photosensitive paper as well as all splicing and cutting operations necessary for the exposed and developed film and the exposed and developed photosensitive paper are dealt with in one small scale minilab. This minilab is able to process small to medium numbers of films.
- On the other hand, large scale photofinishing laboratories are able to process a huge number of exposed films which are arranged in film batches. These film batches are processed in special high speed printer devices.
- In minilabs it is useful to conduct most of the operations, if not all operations, automatically without wasting time.
- Minilabs include one compartment directed to the development of the exposed film and one compartment directed to the development of the exposed photopaper. In the known minilabs as well as in the known types of large scale photofinishing laboratories, replenishment of the development compartment is not sufficiently operated automatically and some times has to be replenished, if the developer solution in the development compartment is no longer useful for an acceptable result.
- Accordingly, it is an object of the present invention to improve on the known arrangements by providing an arrangement for preparing a liquid developer solution for the development of photosensitive material having the features set forth in the preamble of claim 1. In particular, it is an object of the present invention to propose such a new arrangement which is able to provide a fresh developer solution without any time delay.
- The solution to deal at least partially with these objects is set forth in claim 1.
- Particularly useful and advantageous embodiments of the invention are set forth in the sub-claims.
- The advantages of the present invention are based on the fact that an additional mixing tank is located between a supply portion, a reception container and a storage container, wherein said parts are connected to the mixing tank by conduits. With this new feature of the invention, it is possible to prepare a new developer solution on the basis of dry components in connection with the solvent, which will usually be water or distilled water, while, at the same time, when mixing the new liquid developer solution, unused and active liquid developer solution is available for the development compartment of a development apparatus in a minilab or in a large scale photofinishing laboratory. Correspondingly, if the fresh liquid development solution has been pumped or withdrawn from the storage container to the development compartment of the development apparatus, the prepared fresh developer solution from the mixing tank can be supplied to the storage container and, immediately afterwards, the components of the development solution can be introduced into the mixing tank to prepare a new charge of the liquid developer solution. This is in particular important if dry ingredients in the form of powder or granules have to be disoluted in the solvent, e.g. water, which takes considerable time which can delay the overall function of the respective development apparatus and, correspondingly, of the complete minilab or the complete large scale photofinishing laboratory.
- It is an advantageous embodiment of the present invention that the supply portion includes at least one and in particular two or more connecting locations for connecting replaceable vessels to the arrangement according to the arrangement. The vessels are, for instance, replaceable cartridges or the like which can be placed at the connecting locations to introduce the dry component or components or mixtures of the dry components to compose the liquid developer solution. For instance, the connecting locations can include flange devices or the like in connection with a pivotable lid or similar, which can be opened after the flange device has been fixably connected to the connecting location of the supply portion. The replaceable vessels or cartridges can be protected by housings to avoid possible damaging of the cartridges which could soil or spoil the liquid developer solution.
- According to an advantageous embodiment including features in accordance with the invention, the storage container includes a sensor means which is able to monitor at least one particular level of the developer solution. This particular level of the developer solution in the storage container can also be merely a signal indicating that the storage container is empty. Of course, the sensor means in the storage container can also provide a continuous measurement showing all possible levels; i.e. the full level, all intermediate levels and also the empty state of the storage container.
- According to another important embodiment in accordance with the present invention the mixing tank also includes a sensor means which is to monitor at least one particular level of a solvent and/or a liquid in said tank. Also this sensor means can provide a signal when the mixing tank is empty, i.e., if the fresh developer solution has been forwarded to the storage container. On the other hand, the sensor means of the mixing tank can also provide a signal when the mixing tank has been filled with a particular amount of material to be mixed to obtain the homogeneous fresh developer solution. Of course, this sensor of the mixing tank can also issue signals for all intermediate levels between the two levels, i.e. the maximum level and the minimum level. The maximum level should be adjustable so that it is possible to change the maximum amount of developer solution to be prepared in the mixing tank.
- Accordingly, also the reception container should include a sensor means capable of detecting the level of the solvent, e.g. water, distilled water, or the like, in the reception container. It is also possible to only monitor the empty state of the reception container.
- The storage container is connected via a conduct to said development compartment of the development apparatus, minilab or similar. Through this condridge said developer solution can be transported. This can be realised by sucking the developer solution or by creating a pressure in the storage container. If the storage container is placed above the development compartment, it is also possible to transport the developer solution by gravity only. However, a pumping means can be operated to transport the developer solution from the storage container to the development compartment.
- To initiate the transport of the developer solution from the arrangement according to the invention to the development compartment, the development compartment should include a sensor indicating, when to change said developer solution. This sensor in the developer compartment should monitor the activity of the developer solution in the development compartment. If necessary, several sensor means for monitoring the activity of the developer solution in the developer compartment can be used to provide the necessary signals to activate the change of the old developer solution in the developer compartment to the fresh developer solution from the arrangement according the invention.
- In a very secure but simple embodiment, it is possible that the sensor located in the storage container issues a signal when this container is empty. This signal can activate a valve to open a passageway from the mixing tank to the storage container to replenish the storage container. The sensor means installed in the mixing tank can also release a signal when the mixing tank is empty so that a valve is opened to replenish the mixing tank, if necessary, via a pump or the like, containing the solvent which has been supplied from the reception container. At the same, time the signal emitted by the sensor means of the mixing tank can also activate, i.e. open, the supply portion and the respective connecting locations of the supply portion. Afterwards, when the mixing tank has been filled to a certain level with the solvent and the dry components or mixtures from the supply portion and the replaceable vessels or cartridges respectively, the supply portion can be closed and the valve and/or pump can be controlled to stop feeding the solvent. At the same time or somewhat later a mixing device can be activated to support the dissolution process which takes place in the mixing tank. The mixing device can be, for instance, a stirring device or a loop-like convict with the pumping means or the like which generates a continuous movement in the solvent in the mixing tank to enhance the effectiveness of the dissolution process, i.e. to speed up the dissolution process.
- In the following, the invention will be described in more detail with reference to a particular embodiment in accordance with the invention. In the specification, further advantageous aims and features in accordance with the invention are disclosed.
- The attached figure shows an arrangement in accordance with the present invention in a principle cross-sectional view.
- In the figure, a storage container 10 is connected via a sucking
pipe 32 and a pumping means 46 to apipe connection 30 which ends in a developer compartment represented by thereference number 14. - When the pump, which for instance can be a transfer bellow pump, has emptied the storage container 10, a
sensor 52 is able to detect this state of the storage container 10. The sensor holder of thesensor 52 can also include avent pipe 50 to allow a pressure balance in the container 10 when developer is withdrawn or supplied to the tank 10. - The tank 10 has an inlet opening 38 which is connected to an outlet opening 34 of a
mixing tank 18. The outlet opening 34 is connected to the inlet opening 38 via a three-way-valve 54 which can be switched in two different positions. In one position the three-way-valve 54 provides a connection between themixing tank 18 and the storage container 10. In the other setting, thevalve 54 connects the outlet opening 34 of atank 18 to a connectingpiece 42 of thevalve 54. Said valve is fitted via a pipe to apump 40 which has the purpose of moving the liquid in thetank 18 by sucking the liquid to the outlet opening 34 and re-feeding the liquid through anotherinlet 36 of themixing tank 18 back into the mixing tank. Accordingly, thepump 40 generates a movement or flow in the tank to support any chemical reactions, such as for instance a dissolution of components introduced into thetank 18, and to help to provide a homogeneous developer solution which is composed of the solvent stemming from areception compartment 16 and the dry components stemming fromcartridges - The
mixing tank 18 has two inlet openings. The inlet opening 56 connects asupply portion 12 to themixing tank 18. Theinlet opening 48 introduced the solvent from thereception container 16 through apipe 20 into themixing tank 18. - The solvent in the
reception container 16, which can be replenished via anopening 72 into thecontainer 16 is withdrawn via a suckingpipe 22. The suckingpipe 22, which is connected to theconnection pipe 20, is connected to thecontainer 16 via anopening 24. Theopening 24 also supports asensor 74 fixed to a holder through which avent pipe 76 is also connected to the inner space of thecontainer 16. Thevent pipe 76 allows for pressure balance in thecontainer 16 when the level of the solvent in thecontainer 16 changes. The solvent can be transferred by a pump means 26 and the connectingpipe 20. To exactly control the amount of solvent to be supplied to themixing tank 18, a valve, and in particular asolenoid valve 28, can be installed in the course of the connectingpipe 20 behind thepump 26. - In addition, the mixing
tank 18 includes alevel sensor 68 which is able to detect the levels of the amount of liquid existent in thetank 18. Moreover, the fixture of thelevel sensor 68 is provided with avent pipe 70 to allow for a pressure balance in thetank 18. Thelevel sensor 68 and thevent pipe 70 are introduced or connected, respectively, to the inner space of thetank 18 via anopening 64. - The
supply portion 12 has several connectinglocations replaceable cartridges replaceable cartridges locations lids - As can be seen, the
replaceable cartridges housings - All the
sensors sensor 52 can actuate the three-way-valve 42 or alternatively a two-way-valve to replenish the container 10 with fresh developer from the mixingtank 18. In case of the appliance of a two-way-valve, the mixing loop including thepump 40 is always open and only an additional connecting conduit between the mixingtank 18 and the storage container 10 is controlled by such a two-way-valve. Thepump 46 can be activated by one or several sensors in the development compartment, if the used developer in the development compartment has been poured out and fresh developer from the container 10 has be replenished into thedevelopment compartment 14. Thesensor 68 can detect when the mixingtank 18 is empty and can, after thevalve 54 has been closed, activate thesolenoid valve 28 and, if necessary, thepump 26, to introduce solvent, e.g. water, from thecontainer 16 into thetank 18. At the same time, the signal from thesensor 68 can activate thesupply portion 12 to introduce the necessary amount of dry ingredients for the developer solvent into thetank 18. - When the
level sensor 68 detects that the maximum level has been reached, or, if possible beforehand, thevalve 54 can be controlled to be set to connect a mixingpump 40 to themixing tank 18. - Of course, the different functions said forth above can also be accomplished by a central control processor or a central control computer which is part of the development apparatus or the minilab which incorporates the
development compartment 14. - To be able to provide a turbulent stream or flow in the
mixing tank 18 to dissolute the granules more quickly, theinlet 36 can be connected to one or more distribution conduits. This or these distribution conduits can be extended to different locations in themixing tank 18. It is also possible to use one distribution pipe, extending from one end of the mixingtank 18 to the other, said pipe being provided with many orifices to deliver the content of the mixingtank 18 during the mixing and dissolution procedure. - It is also possible to install a distribution arrangement for the granules so that the granules are initially widely spread in the
tank 18 before the mixing or dissolution procedure begins.
